ELECTRICAL FIXTURE.

SPECIFICATION forming part of Letters Patent No. 266,549, dated October 24, 1882.

(No model.)

To all whom 'it may concern Be it known that I, LUTHER S'iIEEiNGER,

l ot New York city, in the county and State of New York, have invented a certain new and useful Improvement in Electrical Fixtures, of which the following is a speeitieation.

The object I liavein viewis such animprovenient in the sustaining-joints ot' fixtures for electric lamps that the lixtures can be supported or suspended t'roin the gas-pipe ot" a house, and the gas used in other fixtures, the ljoint being constructed to shut ott'Jhe gas at the xture, and to allow thewires to he passed into or out of the fixture l'or wiring the saine internally without passing through such gaspipe; and my object is, further, to produce a sustaining-joint by which the xture can be secured to a pipe projecting from the wall or ceiling without turning the fixture itselt' and without danger ot' the tixture heilig accidentally turned while in position, and of cutting' the wires or abradiiig the insulating covering` of the wires.

Means i'or carrying out the invention are shown in the accompanying drawings, in which- Figure 1 is a sectional view of a supportingjoint embodying both features ot the invention. Fig. 2 represents the meeting faces ot' the special union used in the joint, and Fig. 3 is a sectional view ot' a inodiu'ed i'orin of the joint.

A is a pipe projecting from the wall or ceiling B, which -pipe may be the gas-pipev ot' the house; and C is the arm of a bracket or the stem ot' a chai'idelier, through the interior of which pass lthe main fixture wires l 2, which are joined tothe wall or ceiling wires 3 el, running to the tixturc alongthesurt'ace of the wall or ceiling, or carried within the wall or ceiling, and projecting outwardly through one or more holes close to the pipe A.

Dis a jointprovided with a i'einale or male screw-thread, and turning upon or into A. This joint is provided with a solid portion, a, which closes the end ot' A and prevents the escape of gas therefrom, thus allowing ordinary gastixtures or combined gas and electric light lixtures to be used in the same house with the electric-light fixtures. rBhe joint I) is provided with one or more openings, b, of the proper size and shape to permit conducting-wires to be readily passed through the saine without passing through the gas-pipe, and the joint also has an internal bore, c, extending t'roni its outer end to the solid portion a, through which the wires from the arin or stein C pass; or instead ot' a central boi-e and one or more openings extending into it the joint may be provided with one or more slots in its side, along which the wires t'roin the interior ofthe fixture will run. A shell, cap, or canopy, E, covers thejoint7 and the wires l 2 and 3 4L are joined within the cap or canopy, as shown. To permit ot atiaehing the lixture to the supporting-pipe without turning the tixture, the supporting or sustaining point has another section, F, which is preterably what is known in the gas-fixture trade as a union, but which is provided with means to prevent the accidental turning ot' the fixture in use, and the consequent cutting or abradingot' the insulating covering ol" the condnoting-wires. The union is composed ol parts d c, which are joined by a screw-cap, rIhe part d has a inale screw-tliread, with which a teinalethread on the cap f engages, and the part c has aslioulder against which a ilangc on the cap takes. The parts (l and c arepiovidedon their meeting faces with engaging depressions and ribs g li, which prevent the fixture from turning at the union, or a pin or pins on one part and a corresponding hole or holes on the other ,may be used for the purpose. Ihe wires l 2 pass through this union.

Instead ot' the pecuiarly-eonstrueted union, the joint shown in Fig. 3 inay be employed. ln that construction the arin or stein G has an angular socket, i, in which tits a similar plug, k, the parts being held together by a set-screw, l. The plug k may have a central bore, through which the wires l 2 pass, or it may be slotted for that purpose.

It is evident that the two parts et' the supporting-joint could be used separately, it' desired, or combined in a singlejoint, as shown.

What I claiin isl. The combination, with the gas-pipe ot' a house, of an electrical tixture having a hollow arm or stein supported troni such gas-pipe, means for closing the end ot' the gas pipe at the wall or ceiling to prevent the escape of gas, and insulated electrical conductors forming the two parts of the circuit passing through IOO the interior of such hollow arm or stem, but outside of seid gas-pipe, substantially as set forth.

L. The combination, with the gas-pipe ot a house, of an electrical fixture having a hollow urm or stem supported from such gas-pipe, :t supporting or sustaining joint connecting said arm or stem with said gas-pine, and closing the end of such gas-pipe at the wall or ceiling, an opening or openingsin such jointleading to the interior ot' the hollow arm or stem, and insulated electrical conductors forming the two parts ofthe circuit, passing through such opening or openings into or out ot' the arm or stem and extending through the interior of said hollow arm or stem, substantially :is set forth.

3. The combination, with a supporting-pipe, of an electrical fixture, conducting-wires carried by such fixture, u joint connecting the lixture and supporting-pipe, means for permitn ting the connection and disconnection of the fixture and pipe without turning such fixture, and means for preventing the turning` of the ixture in use, substantially as set forth.

4. The combination, with a supporting-pipe, :L xtnre, und cond noting-wires carried by such iixture for supplying electric light, ot' n connecting-joint composed of two parts, and :i loose screw-collar securing them together without turning either part, the meeting 'farces ot' the two parts having means for locking them against turning independently, substantiullbv as setforth.

'lhis specification signed and witnessed the 31st day ot' May, 1882.
